SHEET=M ETAL. ROOFING.

SPECIFICATION forming part of Letters Patent No. 2,589, dated November 1, 1887.

(No model.)

To aZZ whom it 722.07 concern;

Be it known that. I, J osnrn A. Annnnws, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sheet-Metal Roofing, of which the following is a specification.

The several features of my invention and the advantages arising from their use, con- IO jointly or otherwise, will be apparent from the following description.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective View of a sheet of metal embodying my improvements. Fig. 2 is a perspective view of part of a sheet, showing its attachment to the triangular block. Fig. 3 is a perspective view of two sheets adjusted in position to be united. Fig. 4 is a perspective view illustrating the completed joint between the two sheets. Fig. 5 is a perspective view of a modification of my device. Fig. 6 is a perspective View of the separate hook-clcat used in the modification. Fig. 7 is an end view of thejunction of two sheets, illustrating a slight modification in the conformation of the flange B.

The sheet A is provided at one side with the upturned flange B, the top of which is turned over, forming the flange O. The other side of the sheet A is provided with the up-- turned flange D, the top of which is turned upward, forming the flange E. E may be at an angle, substantially as shown in Figs. 2, 3, and 5, or be vertical, as shown in Fig. l. \Vhere the sheets are to be shipped in quantities, it is desirable that the flange E be vertical, because the sheets can then be nested and space economized during their transit. A number of cleats, F, are cut in the flange E, as shown in Fig. 1.

The flanges B and D make oblique angles withthe plate A, so that when joined the triangular block G is accommodated between them.

The joint is made in the following manner: The flange D is adapted to the inclined face of the block G, and the cleats F turned over and fastened to the opposite face of the block G, as shown in Fig. 2. The adjoining sheet is now placed, as shown in Fi 3, with the This flange ridge B O overlapping the upwardly-projecting flange E. The flange B rests against the inclined face of the block G, and is high enough to overlap the flange E, while the sheet A, to which it belongs, lies in the same plane with the adjoining sheet A. The flanges B and O are now crimped together, clamping the flange E between them. They are then turned down and flattened against the face of the block G, as shown in Fig. 4:.

In the modification shown in Fig. 5 the cleats F are not cut in the flange E, and as a means of securing the sheet to the roof a separate hook-cleat, H, is employed. This cleat H is secured to the roof by nails driven through the tang h, and its hook end h overlaps the flange E, as shown in Fig. 5, and is crimped against this sheet with the flanges B O of the next sheet. In the modification shown in Fig. 7 the upper part of the flange B is bent from its inclined position to a vertical one. This enables the flange B to lie flat against the block G, and also flat against the flange E of the adjoining sheet.

The sheets are at each end locked together in any suitable manner and by any suitable means. One common mode of locking them together is shown in the drawings, and consists in providing the sheet with the slits I, which latter separate the cleats J, these cleats forming the usual interlocking joint.

In practice the cleats F are made at the time of use, being easily cut with ordinary snips. The triangular seam forms an excellent watershed, and the folded seam, being at the top of the triangle, is effectually protected from rain.

The sheets are economical of manufacture and are quickly prepared, and when so constructed and put together form a very desirable and durable roof.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The sheet A, provided with flanges D and E, and cleats F, cut in flange E, substantially as specified.

2. The combination of the sheet A, provided with flanges D and E, cleats F, cut in flange E, and block G, substantially as set forth.

3. The sheet A, provided on one side with with the triangular block G, substantially as I I flanges B and G and on the other side with I set forth.

flan es D and E, and cleats F cut in flange E substantially as set forth. 7 l JOSEPH ANDREWS 4. The sheet A, provided on one side with Witnesses:
